Students kit Primary chemistry
Why does the sugar in the tea vanish after stirring? Why do blobs of grease float on the top of the soup while the noodles sink to the bottom? Why does sherbet dropped into water create a lot of fizz? For children water is part of their everyday lives. And they notice and watch these phenomena. Some of them how substances behave in water can be explored with this box.
By mixing water with various substances and conducting experiments under varying conditions, the students can investigate how the substances behave and identify any similarities or differences. This develops a systematic, networked and sustainable way of thinking that also gets students making the right connections and coming to the right conclusions.
The experiments follow a common theme, becoming increasingly difficult as they go on.
Age 10-12

Teachers manual What happens when we mix water with ...?
-
The manual includes basic information on the topic and the organization of workstations for the teacher.
It also contains information about the scientific background, didactic notes on each experiment and student worksheets. - Including a list of materials and rules for experiments.
With copy templates covering 10 workstations.
These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.
This experiment lets students investigate the thermal changes that occur when certain substances are added to water.
The first experiment is designed for students with no previous experience of experiments. It uses common household materials. At this stage, the topic reflects everyday experiences and is an introduction to acting and thinking scientifically.
In this second experiment the students encounter the same phenomena, but with a stronger emphasis on laboratory-style work.
These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.

This experiment revisits the theme of solubility before moving on to crystallization.
This experiment looks at the solidification of water caused by the addition of substances that form a gel.
This experiment leads into a new chapter of Research and Explore focusing on “sherbet”.
